METAL PLANER.

Application filed September 12, 1919. Serial No. 323,349.

To all whom it may concern:

Be it known that 1, Lewis M. PYLE, a citizen of the United States,residing at Bryn Mawr, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements in MetalPlaners, of which the following is a specification. I

This invention relates particularly to planers which are so large andheavy that certain of the adjustments thereof cannot be readily made byhand as has been customary. One of the adjustments that has heretoforebeen necessary to make by hand is the swiveling of the tool carryingdevices with respect to the saddles so as to rovide for feeding at anydesired angle. ne object of the invention is to provide power operatedmeans whereby the tool carrying devices can be swiveled, these poweroperated means being under easy manual control.

Another object of the invention is to provide improved feed mechanismadapted to be readily adjusted to provide coarse or fine feeds. Asconcerns this feature the invention is equally applicable to both largeand small laners.

Other ob ectS of the invention will appear from the followingspecification and claims.

In the accompanying drawings. there is shown the embodiment "of theinvention that is deemed preferable, but it is to be understood thatvarious changes may be made without departing from the spirit of theinvention as set forth in the claims appended to this specification.

Of the drawings:

Fig. 1 is a fragmentary side View of a planer embodying the invention.

Fig. 2 is a fragmentary front view.

Fig. 3 is a rear view of one of the saddles and associated devices.

Fig. 4 is a side view of the parts shown in Fig. 3, this view beingpartly in section along the line 4:4.

Fig. 5 is a sectional view taken'along the line 55 of Fig. 3.

Fig. 6 is a horizontal sectional view through the feed mechanism alongthe line 6-6 of Fig. 7.

Fig. 7 isa side view of the feed mechanlsm.

Referring to the drawings, '1 represents the bed of a planer and 2 thework carrying table which is longitudinally movable along the bed in theusual way. For'reciprocatingthe table any suitable mechanism may beprovided, but preferably there is an electric motor 3 which is directlyconnected with the table and which is repeatedly reversed to drive thetable forward and backward. For efiecting the reversals of the motor 3there is provided a ilot switch 1 which is adapted to be turne by alever 5. Do 6 and 7 are adjustably mounted on the tab e in position toengage the lever 5 and thus move the pilot switch and reverse the motor.

Positioned at the sides of the bed 1 are uprights'88 and these areconnected by an arch 9. Vertically adjustable along suitable guidewayson the uprights is a cross rail 10. For effecting vertical adjustment ofthe cross rail there are provided screws 11-11 which are connected attheir upper ends with a transverse shaft 12 by means of bevel gearing13-13. Any suitable mechanism may be provided for rotating the shaft 12,but as illustrated use is made of an electric motor 14' mounted on thearch 9. The motor is connected with the shaft by means of suitable powertransmitting mechanism including a manually operable clutch, these partsnot being shown in detail, as they constitute no part of the presentinvention.

Transversely movable along the cross rail 10 are two tool heads 15 and16. For moving the tool heads and for controlling them there areprovided three shafts 17, 18 and 19 which extend longitudinally of thecross rail and are rotatably mounted therein. The upper and lower shafts17 and 18 are threaded and are provided with spline grooves and thecentral shaft 19 is provided with a spline groove for :purposes to beset forth.

If desired, additional tool heads may be mounted on the uprights forvertical movement in the usual way. Such side heads are not illustrated,asit will be sufiicient to illustrate and describe the invention as ap-.

- a saddle 20 which engages -guides 'formedon' plied to the cross heads15 and 16 The two.

heads 15 and 16 are similar and'a description of one of them, as forinstance 15,"will suflice for both. 'As illustrated in a general way inFigs. 1 and 2and in greater detail in Figs. 3, 4 and 5,]ea'ch headincludes the crom rail.

Carried by the saddle are tool carrying devices inc uding a bracket 21which is swiveled for movement about an axis extending in the directionof the table reciprocations. This bracket is held in position and guidedby means of tongues 2222 and T-bolts 23--23 enterin a circular T-slot 24formed in the saddle. he swivel bracket 21 is provided with a guidewaywhich is norbe conveniently turned, the upper p mally vertical and aslide 25 is lineally movable along this guideway. For moving the slidethere is rovided a screw 26 which extends longitudinally of the slideand which is bodily movable therewith. The screw has threaded engagementwith a nut 27. Means including bevel gearing 28 is provided for manuallyturning the screw and it will be seen that when the screw is thus turnedthe slide will be moved longitudinally. Mounted on the slide 25 is aswivel plate 29 which is movable about a pivot at 30. In order that theplate 29 may art thereof is arcuate in form and is prov1ded with wormteeth 31 Mountedon the slide 25 is a worm 32 which meshes with the wormteeth 31. It will be seen that when the worm 32 is rotated the swivelplate will be turned about its horizontal axis of adjustment. Mounted onthe swivel plate 29 is a clapper box 33 to which the cutting tool may besecured in the usual manner, as for instance by means of bolts 34-34.The clapper box 33 is connected to the swivel plate 29 by means of anormally horizontal pivot pin 35. The clapper box with the tool can moveabout this pin, thus permitting the tool to swing out .of engagementwith the work during the return stroke of the planer table and to effectrelief.

For moving the saddle along the cross rail either preliminarily forpurposes of adjustment or during operation for the purpose of feeding,use is made of one of the before mentioned threaded shafts, in this casethe shaft 17. Secured to the saddle at the rear thereof is a nut 36which projects into the longitudinal recess in the cross rail in whichseveral shafts are located. This nutengages the shaft 17. It will beseen that when the shaft 17 is turned the saddle and the parts carriedthereby are moved longitudinally along the cross rail. For the otherhead 16 the construction is similar except that the shaft 18 is engagedso that rotation thereof will move the head.

to effect final adjustment. I -this mechanism comprises a gear 36splined The shafts 17 and 18 are ordinarily turned by power as willpresently. appear. However, in making preliminary adjustments it *isdlfiicult to exactly locate the saddles by means of the ower devices.There is therefore prefer-ab y provided-a mechanism located at each toolhead whereby the .head maybe moved manually to a slight extent Asillustrated,

on the shaft 17, this gear meshing with a gear 36"." This latter gearcan be manually turned by means of a handle applied to a squared shaft36. 3 v

For movin the slide 25' by power, use ,is made of the s aft 19. Splinedon this shaft is a bevel gear 37 which is adapted to mesh with a bevelgear 38, this second bevel gear being rotatably mounted in a bearing inthe saddle 20 with its axis coincident with the axis of adjustment ofthe swivel bracket 21. Connected with the bevel gear 38 is a bevel gear39 which meshes with a bevel gear 40 connected with the nut-27. .It willbe'seen that when the shaft 19 is turned the nut 27 may also be turnedwith respect to the screw, thus moving the slide 25 upward or downward.Inasmuch as the axis of the bevel gears 38 and 39 is coincident with theaxis of adjustment of the swivel bracket 21,

the bracket can be freely adjusted without interfering with the powerconnection. In order that the same shaft 19 may serve for both heads,means is provided whereby the drive gear 37 for either head may beconnected to or disconnected from the correspondmg driven gear 38. Asillustrated, the gear .37 is slidable with respect to the saddle underthe control ofa hand lever 42. It will be seen that by this mechanismthe gear 37 can be brought into or out of mesh with the gear 38, thuscompleting or breaking the power connection. I

For operating the several shafts 17, 18 and 19 there is provided animproved mechanism which is mounted on one end of the cross rail. Thismechanism preferably receives its power from an independent electricmotor, which motor may be the aforesaid motor 14. As illustrated, thereis provided a shaft 43 which extends transversely of the planer andwhich is directly geared to the motor 14. By means of bevel gearing at44 this shaft is connected with a vertical shaft 45 adjapent one end ofthe cross rail. Splined on the shaft 45 and vertically movable with thecross rail. is a bevel gear 46 which meshes with a bevel gear 47 on ahorizontal shaft 48 rotatably mounted in a casing 49 carried by thecross rail. This shaft 48 constitutes the initial power ele ment on thecross rail.

For effecting intermittent feeding the following mechanism is provided.Secured to "insurer f adapted to engage the teeth oia gear 56 ro-'tatably mounted on the shaft 54:. It willbe seen that when the shaft isrotated, the bell crank 53 is given an oscillatory movement and the bellcrank by means of the pawls 55 serves to turn the gear56 intermittently.The gear 56 constitutes an intermittently operating power feed element.

The gear 56 meshes with a gear 57 loosely mounted on a shaft 58 parallelwith the shaft 54. Rotatably mounted on the shaft 57 and is a-third gear61.

54;- is a gear 59, this gear being adjacent the gear 56 and connectibletherewith. The gear 59 meshes with a gear 60 loosely mounted on the.shait-58. l't will be observed that the gear 59 is smaller than the gear56 and that the gear 60 is larger than the gear 57.-

Mounted on the shaft 58 between the gears This gear is slidably mountedon the shaft and is movable under the control ofa hand lever 62. Clutchteeth 63 are interposed between the gears 57 and 61 and similarclutchteeth 64; are interposed between the gears 60 and 61.

' It will be seen that, in acordance with the present invention, thereare two'difi'erently speeded trains of power transmitting devicesbetween the power element or gear 56' and the ear 61 and that the lastsaid gear 61 can be turned at each actuation of the gear 56 through arelatively large angle by means of the clutch teeth 63 or through arelatively small angle by means of the clutch teeth 64-.

one end the gear 61 meshes with a gear 65 mounted on a shaft 66, thisshaft also carrying a gear 67. Rotataoly mouiited on a shaft 68 are twosimilar gears 69 and 76 which mesh respectively with the aforesaid gear67 and the aforesaid gear 61. The gear 69 meshes with gears 71, 72 and73 loosely mounted respectively on the shafts 17, 19 and 18. The othergear 70 meshes with similar gears 74, and 76 also mounted respectivelyon. the said shafts 17, 19 and 18. From a study of the gearing which hasbeen described, it will be seen that the two gears 69 and 70 are rotatedin opposite directions and thatthe sets of gears 71, 72 and 73 and 7t,75 and 76 will also be rotated in opposite directions. Mounted on eachof the shafts 17, 19 and 18 is a clutch element 77 adapted to be movedby a hand lever 7 8. Each clutch element is splinecl on its shaft, asfor instance 17 illustrated in Fig. 6, and it can be engaged either withthe gear 71 or with the gear 74:, thus connecting the shaft for rotationin either direction as desired- When the mechanism is to be used forfeeding, the shaft t5 is given one com lete revolution at the end ofeach table reciprocation, this being preferably brought about byoperating the motor to a definite extent by suitable electricalcontrollin devicesoperated by the planer table. t each such revolutionot'the shaft 45 the gear 56 is ro-- tated through a definite angle whichangle can be varied by chan' 'ng the adjustment of the crank pin 51. aremoved in opposite directions. through. definite angles corresponding tothe angle of movement or the gear 56, the extent of he gears 69 and 70movement being adjustable by moving the gear 61 to engage and disengagethe clutch teeth 63 and 65. Thus the gears 71, 7 2 and 73 are turned inone direction and the gears 74:, 75 and 76 are turned in the otherdirectron. By properly adjusting the several clutch elements 77,theseveral shafts 17 19 and 18 can '0 turned in either direction asdesired, thus eilecting transi' erse feeding of either head in eitherdirection or effecting vertical feeding of either or both of the toolsin either direction.

F or continuously moving the tool heads or the tools to effectpreliminary adjustments the following mechanism is provided. Secured tothe. aforesaid shaft as is a gear 79 which meshes with an idler gear 80which idler gear in turn meshes with a gear 81 loosely mounted on theaforesaid shaft '54: and constituting a driving element for use duringpreliminary adjustments. lit will be seen that when the shaft 45 iscontinuously rotated, the gear 81 is also continuously rotated. it willbe observed that the gear 59 is located between the gears 56 and 81..Clutch teeth 82 are interposed bet-ween the gears 56 and 59 and similarclutch teeth 83 are interposed between gears 81 and 59. The gear 59 canhe moved longitudinally by means of a hand lever at to engage the teethat 89? or the teeth at 83 as desired. Thus the gear 59 can be caused torotate intermittently with the gear 56 or continu ously with the gear81.

V7 hen the mechanism is to be used for the preliminary adjustment of thetool heads, the clutch teeth at 83 and also those at 6% are engaged andthe shaft 45 is operated continuously. The several gears71, 72 and 73and 74's, 75 and 76 are then rotated contlnuously but in oppositedirections. By properly adjustin the clutch elements 77 any of theshafts 1 19 and 18 can be turned a erably operated by the power feedmechaall nism which serves to move" the saddle and the tool carryingdevices in the way already described. As illustrated, use is made of thebefore mentioned shaft 19. Mounted on this shaft is a worm 85whichmeshes'with a Worm wheel 86 mounted on the saddle and rotatableabout an axis parallel wit-h the axis of adjustment ofthe swivelbracket. Connected with the worm wheel 86 is a pinion 87. This pinion 87meshes with gear teeth 88 formed. on the bracket 21. It will be seenthat when the worm wheel 85 is rotated by means of the shaft 19, powerwill be transmitted to rotate the gear 87 and thus turn the bracket 21and the parts carried thereby. In order that the movement of the swivelbracket may be manually controllable, there is provided a clutch 89between the shaft 19 and the worm 85. Preferably use is made of thebefore mentioned slidable bevel gear 37, clutch teeth being formedthereon at 89 which are adapted to be moved into or out of mesh by thebefore mentioned lever 42. Thus the same hand lever serves either tomove the gear 37 into mesh with the gear 38 for the vertical movement ofthe slide 25 or serves to engage the clutch teeth at 89 for theswiveling of the tool carrying devices.

It is difficult to secure exactly the desired adjustment by means of thepower mechanism and there is therefore provided manually operable meanswhereby final adjustment may be effected. For this purpose there isprovided a gear 90 connected with the worm 85, this gear 90 meshing witha gear 91. Gear 91 may be turned manually by means of a handle appliedto a shaft 92.
